Here is described a time of delicate change, from Late Antiquity to Middle age.
There are two main factors: firstly, the continue pressure of many populations along the borders of the Empire, secondly the diffusion of Christianity, which is progressively replacing many religions (particularly from the Edict of Constantine of 313 A.D.).

In this period begin to develop forms of religious architecture adequate to the new religion, so every previous building, ritual and iconography are reinterpreted in this way.

In Versilia, Acquarella’ s farm (Capezzano), is maintained as an olive oil productive center till the 6th century, as witnessed by potteries in “Terra sigillata” (the crystalline red shiny coating) from Africa, coins and glasses..
